Congruent. Exactly equal in size and shape. Congruent sides or segments have the exact same length. Congruent angles have the exact same measure. For any set of congruent geometric figures, corresponding sides, angles, faces, etc. are congruent. Note: Congruent segments, sides, and angles are often marked.
Corollaries, &. CPCTC. Isosceles Triangles Has at least 2 congruent sides. The angles opposite the congruent sides are congruent Converse is also true. The sides opposite the congruent angles are also congruent. This is a COROLLARY. A corollary naturally follows a theorem or postulate. We can prove it if we need to, but it really makes a lot of sense. The bisector of the vertex angle of an isosceles Î´ is the perpendicular bisector of the base.
